How it works

Think of magnesium as a key regulator for your body's electrical and structural systems. It supports bone mineralization, which is the process of depositing minerals into your skeleton to keep it strong. Additionally, it promotes neuromuscular relaxation, helping your muscles relax and your nerves signal properly after activity [NIH ODS].

The FDA has received 592,059 total adverse event reports for all products, but specific side effect counts and reports for Bluebonnet Magnesium Citrate 400 mg are not provided [FDA data].

Our recommendation

Start by checking with your doctor to confirm a need for magnesium supplementation. If you proceed, take the 400 mg dose as directed, ideally with food to reduce the risk of stomach upset. Do not combine with calcium supplements or certain antibiotics without medical guidance [NIH ODS].
